Why it's worth studying: Ukkonen's algorithm is still widely-used and widely-taught in a number of cir-
cles because its approach works by exploiting elegant structures inherent in strings. In particular, Ukko-
nen's algorithm revolves around the idea of the suffix link, a link in a suffix tree from one node to another
in a style similar to the suffix links in Aho-Corasick string matching. This algorithm is significant both
from a historical and technical perspective and would be a great launching point into further study of
string algorithms and data structures.
